It is a bourbon barrel aged coffee stout w/ vanilla. I drank it side by side by side with other variations of this brew, Fast Breaker and Hazelnut Fast Breaker. Delicious beer! One of my favorites all weekend. Couldn't decide whether this or Hazelnut version was my favorite. This is a MUST try if you get the chance. There was so much great beer this day between the amazing tap list and the crazy bottle share. Thanks for a great day Peg's.
